Package: apache2 Version: 2.0.52-3 Severity: normal
Looking at http://httpd.apache.org/docs-2.0/content-negotiation.html, I can read this: ======= The server will also attempt to match language-subsets when no other match can be found. For example, if a client requests documents with the language en-GB for British English, the server is not normally allowed by the HTTP/1.1 standard to match that against a document that is marked as simply en. (Note that it is almost surely a configuration error to include en-GB and not en in the Accept-Language header, since it is very unlikely that a reader understands British English, but doesn't understand English in general. Unfortunately, many current clients have default configurations that resemble this.) However, if no other language match is possible and the server is about to return a "No Acceptable Variants" error or fallback to the LanguagePriority, the server will ignore the subset specification and match en-GB against en documents. Implicitly, Apache will add the parent language to the client's acceptable language list with a very low quality value. But note that if the client requests "en-GB; q=0.9, fr; q=0.8", and the server has documents designated "en" and "fr", then the "fr" document will be returned. This is necessary to maintain compliance with the HTTP/1.1 specification and to work effectively with properly configured clients. ======= This looks good except it seems there's a small issue when Apache adds the parent languages. I have a client that requests: "fr-fr,en-us;q=0.3" and the server is configured like this: AddLanguage fr .fr AddLanguage en .en LanguagePriority en fr So, apache is adding the parent languages to the client request because the server is not configured to deal with fr-fr and en-us. However, the client gets the english page. So it seems apache is adding the parent languages in the "en fr" order (the one defined by LanguagePriority). I would expect apache to add the parent languages in the order they appear in the client request, so the user can get the french page. Tell me if you need more informations.
